Patented Jaime, 1920.

Application filed March s, 1916. Serial in. 82,583.

To all whom it may concern:

Be it known that 1, Bone D. BOI-IANON, a citizen of the United States,residing at Boston, in the county of Suffolk and tate of Massachusetts,have invented certain Improvements in Tip-Measuring Apparatus, of whichthe following description, in connection with the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several figures. V V I This invention relates toapparatus for use in the manufacture of shoes and particularly to tipmeasuring mechanism designed for use in connection with the pulling-overoperation as performed by pulling-over ma' chines of the type shown inUnited States Letters Patent No. 1,029,387,.granted June 11, 1912, onapplication of Ronald Mc- Feely, and similar machinesin which the topface of a shoe is visible to the operator during the pulling-overoperation. .As is well understood, one of the steps in the operation ofpulling-over a shoe is the correct positioning of the .rear edge of thetoe cap, commonly referred to as the tip line, longit-udinally of theshoe in order that the length of the toe tips of a given size or styleor of a given pair of shoes may be the same. The requirements of thetrade necessitate that the tip lengths of a pair of shoes besubstantially identical and in order to secure this accuracy it isdesirable to employ mechanical means for assisting the eye of theoperator in measuring the length of the toe cap during the pulling-overoperation.

It is the general object of this invention to provide a tip measuringdevice for pulling-over machines which will be convenient to use, whichnormally will be out of the operators way and with which the tip lengthof one shoe may be accurately compared with the tip length of the nextsucceeding shoe placed on the machine or with which the lengths of thetips of shoes of a given style or size may be compared with a givenstandard.

In accordance with features of the invention the tip measuring device ismounted on a support which is arranged for movement relatively to themachine frame into and out of tip measuring relation to the shoe and hasparts adapted to be set to indicate the tip length of a given shoe,which setting may be maintained and the device applied to the succeedingshoe so that the tip length of that shoe may be made to correspond withthe setting of the device which indicates the tip length of thepreceding shoe or a given standard length.

As shown herein the tip measuring device ismounted for movement aboutafixed vertical axis, located upon the frame of the machine, for movementinto and out of tip measuring position the device, preferably beingcarried byan arm which extends rearwardly and is pivoted to a bracket atone side of and upon the frame of the machine for movement in a planeoblique to the plane of the sole. By this construction the tip measuringdevice is readily movable out of operative position and may be returnedto bring the tip measuring device into the identical position relativelyto the next shoe which it had been made to assume by application to thepreceding shoe before being moved away. l

Another feature of the invention consists in means for mounting the tipmeasuring device so that it may normally be remote from the shoe in thedirection of the length of the shoe and may be brought into tipmeasuring position relatively to the shoe by a right line movementsubstantially parallel with the shoe bottom; Preferably means forholding or looking the device in tip measuring relation to the shoe isprovided. As herein shown, the device is held normally away from theshoe by a spring, and a ratchet and pawl is provided to lock the devicein tip measuring position. By this construction the tip measuring devicemay be set to indicate the length of a given toe tip and that settingmay be maintained for application of the device to a succeeding shoe toascertain what adjustments of that shoe upper are necessary to produce alength oftip substantially identical with that of the preceding shoe orto compare each shoe with a given standard length indicated by thesetting of the tip measuring device.

.These and other features of the invention will appear more fully fromthe following description when read in connection with the accompanyingdrawing and will be pointed out in the appended claims.

In the drawing, I y p H Figure 1 is a side view of a pulling-over Fig. 2is a perspective view of a part of the tip measuring mechanlsm in itsoperative V position'relatively to the shoe held in the grippers of thepulling-over machine;

measuring mechanism;

Fig. 4 is a sectional detail of the adjusting mechanism of the tip lineengaging memher; and

Fig. 5 is a detail view taken at right angles ofFig. 4.

Referring to the drawings, it will be briefly explained that thepulling-over machine comprises toe and side grippers 1 and 3 by whichthe upper is seized and pulled over the last which is rested against ashoe bottom abutment or sole rest 5. A forked heel rest 7 is mounted ona movable carrier by which the rest is yieldingly advanced from aretracted position into engagement with the heel endvof the shoe-afterthe grippers have tensioned the upper and hold the upper firmly againstthe sole rest. Since the toe and side grippers first draw the upper iminished to -vary the position of the tip seam as well as the meansincluding the lever 9 for shifting the upper transversely of the lastand for moving one of the side-grippers forwardly and the otherba'ckwardly for straightening the] tip seam if it does not occupy thedesired angular relation to the median line of the'last, I 7

The tip measuring mechanism embodying this invention comprises an arm orsupport 2 mounted to turn about a pivot '4 on a bracket fixed tothemachine frame at one side thereof, the axis of the pivot extendingparallel with the longitudinal median plane of the shoe. The forward endof the arm 2 has a hole extending in a directionparallel with the shoebottom as the shoe is held in the pulling-over machine, the shoe beingpo sitioned as is usual in machines of this-kind with the upper down andthe sole at an inclination of approximately 35 to the horizontal. In thehole in the end of the arm 2 a stem 6 is mounted for longitudinalmovement and is upheld by a spring'S. A stop piece 10 is held infixedrelation to the lower end of-the stem 6 by a set screw 12 andupwardly extending portions 14 on the stop piece 10 engage flattenedsurfaces of the arm 2 tohold the stem against rotation. Be-

tweenthe portions 14 and pivoted thereto by a pin 16 is a pawl 18' whichengages ratchet teeth 20 formed on the'arm 2. By, this construction thestem (inlay be depressed against the spring 8 and will beheld indepressed position by the pawl 18 until released by the operator. 1 r VThe upper end of the. stem 6 isbifurcated to receive a curved arm 22which is rigidly held therein by a bolt 24. Th e arm 22 is curved to.bring its free end into proper On the free end of the arm '22 is secureda toe 'engaging member 25 constiing'movement a tip seam/locating member"or tip line indicator 28 which has an end graduated as shown toindicate difl'erent lengths of tips. The members 25 and 28 constitutethe tip line indicating means or tip measuring device as referred toherein.-

For adjusting the member 28 for a wider range of lengths of tips than isprovided for by these graduations the member 28 is ara slider26 in whichis mounted-for slidranged for adjustment in the slide'26 andis held indifferent positions of adjustment by a springpin 30 which is arranged toengage any one ofaiseries of staggered holes 32 in the member 28'. Thisis'effected by mounting the spring pin 30 in an arm 34 which is pivotedat 36 to the slider 26. A slot 38 is provided inthe s'lider 26 sothatthe pin may be swung withthe arm 34into position to engage any one ofthe staggered holes 32, Fig.

5. If desired the arm-and pin may be placed in an intermediate positionin which the pin will rest on'the member 28 between the lines of holes32 and will hold the member frictionally inadjusted position. Thenormally fixed angular relation of the arms 2 and 22 scribed to permitpresentation of the tip measuring device properly under diiferentconditions of work.

In the use of the mechanism the shoe is placed in the pulling-overmachine as shown in Fig. 1 and, the machine passed through the firstportion ofits cycle to place the upper under tension. The arm 2 is swungin a horizontal plane about the vertical axis 4' to bring the member 25over the end of'the toe of the shoe. The arm 22 is then depressed in adirection parallel with the shoe bottom against the spring 8 until themember 25 engages the shoe, the member being locked and held in thatposition by the action of the pawl 18 on the teeth 20. The slide 26 ismoved on the member 25 if necessary to ward for a toe of the givenheight, its contact with the toe will push the slide 26 backwardly onthe member 25. The member 28 is then adjusted by withdrawing the pin 30by its head 40 against a spring 42 to free the member 28 which isthen-movedin the direction ofthe length of the shoe to the proper.position to' indicate the right length for the shoe or a series ofshoes. The head 40 is then released and the arm 3a swung to one side orthe other to engage the nearest one of the staggered openings 32 or themember 28 may be held yieldingly in adjusted position by frictionalaction of the spring pin 30 as described. Nhen the tip seam has beenproperly located the mechanism is swung to one side out cit-the way ofthe operator about the axis 4:. The pullingover operation is thencompleted and an other shoe is placed in the machine and its uppertensioned. The mechanism may now be swung back about the axis a into theidentical position it occupied in the treatment of the previous shoe andthe tip adjusted in the wellrknown manner to the length ot the tip ofthe shoe previously pulled over. In case the position of the second shoein the machine is not quite the same as that of the first shoe the pawl18 may be released and the member 25 brought into position over the toeand then depressed to contact with the toe. This, however, may be donewithout disturbing the relative positions of the parts 25, 28, and thetip length indicated by the device will be the same as for the previousshoe.
